[0030] The present utility model will be described in detail below with reference to the accompanying drawings.

[0031] As Figures 1 - 4 shown, a blanking mechanism of a PCB drilling device includes a drilling platform 10. A blanking component 1 is arranged on the drilling platform 10. The blanking component 1 includes a blanking support arm 11 arranged above the drilling platform 10. The blanking support arm 11 is arranged along the moving direction of the PCB board. A blanking support frame 2 is slidably installed on the blanking support arm 11. An adsorption frame 20 capable of moving longitudinally is arranged on the blanking support frame 2. A plurality of suction cups 24 for adsorbing the PCB board are installed on the adsorption frame 20.

[0032] The blanking support arm 11 is installed above the drilling platform 10 and does not occupy the space of the drilling platform 10. The rest of the mechanical equipment on the drilling platform 10 can be arranged according to requirements. When it is necessary to blank the drilled PCB board, the blanking support frame 2 moves along the blanking support arm 11 until it is longitudinally aligned with the PCB board. Then, the adsorption frame 20 descends to adsorb the PCB board through the suction cups 24, and then moves along the blanking support arm 11 to the outside for blanking, ensuring the blanking efficiency without affecting the arrangement of the rest of the mechanical mechanisms of the drilling device.

[0033] Further, the blanking component 1 further includes a blanking transmission member for driving the blanking support frame 2 to move along the length direction of the blanking support arm 11. The blanking transmission member includes a belt transmission member 14 arranged parallel to the blanking support arm 11. One of the long sides of the belt transmission member 14 is installed with a transmission seat 18 along the way. The transmission seat 18 is connected to the blanking support frame 2. Driven by the belt transmission member 14, the transmission seat 18 can reciprocate along the blanking direction of the PCB board. Since the transmission seat 18 is connected to the blanking support frame 2, it can drive the blanking support frame 2 to move along the length direction of the blanking support arm 11, realizing the blanking of the PCB board.

[0034] Preferably, the belt transmission member 14 further includes transmission support seats 15 installed at both ends of the blanking support arm 11. The transmission support seats 15 are installed with belt pulleys 16. A transmission belt 17 is nested between the two belt pulleys 16. The belt pulleys 16 are in transmission connection with the transmission belt 17. One of the belt pulleys 16 is a driving pulley and can rotate forward and backward under the drive of a forward and reverse motor. When the forward and reverse motor rotates forward, the transmission seat 18 can move along the forward direction of the blanking of the PCB board. When the forward and reverse motor rotates backward, the transmission seat 18 can move backward along the blanking direction of the PCB board, reciprocally blanking the PCB board.

[0035] Further, a support guide rail 12 is arranged along the length direction of the blanking support arm 11. A support sliding seat 13 is slidably installed on the support guide rail 12. The blanking support frame 2 is connected to the support sliding seat 13. Through the sliding fit between the support guide rail 12 and the support sliding seat 13, the linear movement stability of the blanking support frame 2 can be further improved, and the stability of the PCB board blanking can be improved.

[0036] Preferably, the number of the blanking support arms 11 is two, and they are arranged in parallel at intervals. The support guide rail 12 is installed at the bottom of the blanking support arm 11. The top of the blanking support frame 2 is connected to the support sliding seat 13, so that the blanking support frame 2 moves at the bottom of the blanking support arm 11.

[0037] The specific structure of the adsorption frame 20: The adsorption frame 20 includes an adsorption plate 21 and a plurality of adsorption strips 22 arranged on the adsorption plate 21. One end of the adsorption strip 22 extends outward from the adsorption plate 21. The suction cups 24 are respectively installed on the adsorption strips 22 and the adsorption plate 21. The plurality of suction cups 24 are arranged on the adsorption plate 21 and the adsorption strips 22 of the adsorption frame 20. When contacting the PCB board, the adsorption area can be increased, and the stability of the adsorption of the PCB board can be further increased. After being lifted, it is not easy to fall off and will not tilt, ensuring that the PCB board is smoothly blanked from the drilling platform 10.

[0038] Preferably, the adsorption plate 21 is formed with a plurality of first installation long grooves 25, the adsorption strip 22 is formed with a plurality of second installation long grooves 26 along the length direction, the first installation long grooves 25 and the second installation long grooves 26 are both slidably installed with sliding installation blocks 23, and the suction cups 24 are respectively installed in the first installation long grooves 25 and the second installation long grooves 26 through the sliding installation blocks 23; the sliding installation blocks 23 can move along the corresponding first installation long grooves 25 and second installation long grooves 26, so that the positions of the sliding installation blocks 23 change, that is, the suction cups 24 installed on the sliding installation blocks 23 can change their positions, and the contact positions of the suction cups 24 with the PCB can be adjusted according to the drilling positions of the PCB, preventing air suction, ensuring that a plurality of suction cups 24 are all adsorbed to the PCB, and ensuring the stability of adsorption.

[0039] Preferably, the adsorption plate 21 is further formed with an installation hole 27 for installing the adsorption strip 22, one end of the adsorption strip 22 is formed with an installation column 28 that is rotationally matched with the installation hole 27, and the adsorption plate 21 is provided with an adjusting member 29 that is tightly connected to the installation column 28; through the installation column 28 being rotationally matched with the installation hole 27 of the adsorption plate 21, the adsorption strip 22 can swing and adjust the angle, that is, the positions of the suction cups 24 will change, further increasing the diversity of the position adjustment of the suction cups 24. After adjusting to the required position, the installation column 28 can be locked with the adsorption plate 21 through the adjusting member 29 to prevent loosening.

[0040] Preferably, the installation column 28 is formed with an external thread structure, and the adjusting member 29 can be a threaded sleeve handle, and the tightness of the installation column 28 and the adsorption plate 21 can be adjusted by twisting the threaded sleeve handle.

[0041] A guide post 291 is installed on the top of the adsorption plate 21, the blanking support frame 2 is provided with a guide sleeve 292 coaxially aligned with the guide post 291, and the adsorption plate 21 is slidably matched with the guide sleeve 292 through the guide post 291. The blanking support frame 2 is installed with a blanking lifting cylinder 293, and the driving end of the blanking lifting cylinder 293 is connected to the adsorption plate 21; when blanking is required, the blanking support frame 2 moves along the blanking support arm 11 until it is longitudinally aligned with the PCB, then the blanking lifting cylinder 293 descends, driving the adsorption plate 21 to descend, so that the suction cups 24 are attached to the PCB and adsorb it, and then the blanking lifting cylinder 293 rises, making the PCB away from the drilling platform 10.

[0042] In summary, it can be seen that the present invention has the above-mentioned excellent characteristics, enabling it to enhance the efficiency that has never existed in the prior art during use and having practicality, and becoming a product with extremely high practical value.

[0043] The above content is only the preferred embodiment of the present invention. For those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manner and application scope. The content of this specification should not be construed as a limitation to the present invention.
